Fundamental Properties of Pervasive Systems

The pervasive systems simultaneous use more than one computational and communication devices with networked enabled services, and the user may not be aware of it. These features totally support and advance desktop paradigm.

Classification of ubiquitous computing has been done and various definitions have emerged. In our daily life, we use many gadgets and computer accessories, they all need the physical interaction of human beings in order to be operational. On the other hand, pervasive or ubiquitous technology is used in such a way where a user is completely unaware of it. The technology will not be visible but will be available and can communicate with other components or devices to facilitate the existence of other devices or humans far away. In the above definition, there is a word called “desktop paradigm”. As per Wikipedia, it is defined as ”In graphical computing, a desktop environment (DE) commonly refers to a style of the graphical user interface (GUI) that is based on the desktop metaphor which can be seen on most modern personal computers today ”

The core concept of pervasive computing is, it is a set of small intelligent devices integrated with each other providing fast and robust network connectivity, data transfer and network processing devices that are distributed regardless the distance and disbursed geographically and facilitate everyday life. As the pervasive systems facilitate the activities of the users as per their requirements, the technology needs to be transparent from the user. For integrating and implementing a solution of ubicomp or pervasive systems and at the same time, making them transparent is not an easy task. Ubiquitous computing or pervasive systems provide a challenge for system designing, engineering, system modeling, and research.
